Property Description

Located in Montastruc-de-Salies, in the heart of a protected natural environment, this former watermill dating back to 1819 offers a truly unique living setting. The river running alongside the property creates a rare, peaceful, and deeply bucolic atmosphere.

Spanning approximately 400 square meters, the building retains all the charm of traditional properties in Southwest France: stone walls, exposed beams, generous proportions, wooden floors, and unobstructed views of the surrounding countryside. The property exudes the feeling of an authentic, warm, and characterful family home.

The house currently offers six bedrooms, including one that is open to the landing but could easily be partitioned off as needed. Two of the bedrooms have their own en-suite bathrooms, and the property has a total of three bathrooms.

The ground floor is arranged around beautiful living spaces, including a large living room with a wood-burning stove, a separate kitchen, a spacious entrance hall, a garage, hallways, and access to the outdoor areas. The generous proportions make it ideal for a large family home, a charming holiday residence, or a hospitality project in a particularly desirable natural setting.

In summary
A characterful former mill, a rare find on the market, offering approximately 400 m² of living space, 6 bedrooms, 3 bathrooms, a swimming pool, 4,000 m² of land, and a river running right along its edge.

A truly atmospheric property, perfect for lovers of historic buildings, nature, and unique properties with a rich history.

Outdoor spaces – river, pool, and nature
The surrounding environment is one of this property's greatest assets.

The river bordering the mill gives the property a truly unique atmosphere. The sound of flowing water, mature trees, natural riverbanks, and the immediate proximity of the forest create a peaceful living environment.

The property is sold with approximately 4,000 m² of land, offering a beautiful balance between space, privacy, and reasonable maintenance. The outdoor areas allow you to fully enjoy the natural surroundings, with various relaxation zones around the house.

The 10 x 5 m swimming pool, with a depth of up to 2.2 m, blends seamlessly into this verdant setting. Chlorine-treated, with a sand filter and a new pump, it provides a true extension of your living space during the summer months.

A waterside terrace with a barbecue offers a charming setting for al fresco dining, overlooking the river and the surrounding vegetation.

Interior Spaces
The house offers generous proportions and an ideal layout for entertaining family and friends.

On the ground floor, there is a spacious living room of approximately 69 m², featuring a wood-burning stove, exposed stone walls, and a warm atmosphere. A separate kitchen, entrance hall, hallways, and additional rooms complete this level.

Upstairs, the property offers six bedrooms, including one open to the landing, which can easily be converted into a closed bedroom if desired. Three bathrooms provide comfortable accommodations, including two suites with private bathrooms.

The hardwood floors, period woodwork, generous proportions, and views of the surrounding nature give the property an authentic, simple, and elegant feel.

The property benefits from a pellet boiler heating system, supplemented by a wood-burning stove in the living room.

The windows are double-glazed, and the shutters were renovated in 2025.

The swimming pool has a sand filter, chlorine treatment, and a new pump.
